[jira] [Commented] (GROOVY-8602) Safe index doesn't work with map arguments

["Paul King (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-8602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16601736#comment-16601736 ] 

Paul King commented on GROOVY-8602:
-----------------------------------

Reducing priority. The only place map indexing is allowed is immediately after a class constant, e.g.:
{code}
assert Date[year: 118, month: 8, date: 3].day == 1
{code}
I don't see a lot of value in supporting this:
{code}
assert Date?[year: 118, month: 8, date: 3].day == 1
{code}
If we supported using a class variable, I could see the value, e.g.:
{code}
def d = Date
assert d[year: 118, month: 8, date: 3].day == 1 // No map entry allowed at this place
{code}
But we don't support this. You could perhaps argue for a slightly better error message in this case.
